Echo: util-linux: security update to 2.41.5-0+deb13u1+e1

medium Tenable Self-Hosted Container Security Plugin ID 457881

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw was found in the libblkid library of util-linux. During nested partition probing, the BSD, Minix,
 Solaris x86, and UnixWare partition probers cache a raw pointer to a parent partition entry in a
 dynamically allocated array. When subsequent partition additions cause the array to be reallocated, this
 pointer becomes stale, leading to a heap use-after-free read. An attacker who can present a crafted block
 device image (for example, via USB insertion or a loop-mounted disk image) can trigger this flaw without
 user interaction, as libblkid is invoked automatically by udev/udisks as root on block-device hot-plug
 events. This could lead to limited information disclosure or denial of service. (CVE-2026-13595)

Solution

Update the util-linux library and its related packages to version 2.41.5-0+deb13u1+e1 or later.
